Risk factors for flap dehiscence and/or necrosis following standard rotational flap in cranial vault osteomyelitis without intracranial involvement: A retrospective study.

Objectives: The study aimed to estimate the incidence of flap dehiscence and/or necrosis (FD/N) following standard rotational flap (SRF) surgery for cranial vault osteomyelitis without intracranial involvement (CVO) and to identify factors associated with these complications.

Methods: A retrospective study was conducted using chart reviews of patients who underwent SRF to cover CVO defects over a 10-year period. Twenty-one predictor variables were analysed, categorised into demographic, health status, anatomic, and surgical factors.

Complications of preseptal versus retroseptal transconjunctival approach for isolated orbital floor fracture repair: A double-blind, non-inferiority, randomized, split-face controlled trial.

Introduction: Effective surgical access to the orbital floor facilitates surgery and mitigates postoperative complications (PC). The aim of this study was to compare PC between the preseptal and retroseptal transconjunctival approaches (PS-TCA/RS-TCA) for isolated orbital floor fracture (OFF).

Materials And Methods: Using a double-blind, non-inferiority, randomized, split-face study design, patients aged ≥ 18 years with bilateral isolated OFF were enrolled.

Pathophysiology, diagnosis, and treatment of membranous nephropathy.

Nephrotic syndrome is in adult patients mainly due to membranous nephropathy (MN) characterized by thickening of the glomerular basement membrane (GBM) and immune complex formation between podocytes and the GBM. Autoantibodies directed against the M-type phospholipase A2 receptor (PLA2R) and thrombospondin 1 domain-containing 7 A (THSD7A) can be used as diagnostic biomarkers. THSD7A seems to be of direct pathogenic significance as is suggested by experimental models and plasmapheresis in humans.

Chylomicronemia from GPIHBP1 autoantibodies.

Some cases of chylomicronemia are caused by autoantibodies against glycosylphosphatidylinositol-anchored HDL binding protein 1 (GPIHBP1), an endothelial cell protein that shuttles LPL to the capillary lumen. GPIHBP1 autoantibodies prevent binding and transport of LPL by GPIHBP1, thereby disrupting the lipolytic processing of triglyceride-rich lipoproteins. Here, we review the "GPIHBP1 autoantibody syndrome" and summarize clinical and laboratory findings in 22 patients.

Platelets in Advanced Chronic Kidney Disease: Two Sides of the Coin.

Rates of thrombosis and bleeding episodes are both increased in patients with advanced chronic kidney disease (CKD). The pathogenic mechanisms of thrombosis in these patients include platelet activation, increased formation of platelet-leukocyte conjugates, and platelet-derived microparticles, as well as effects of uremic toxins on platelets. On the other side of the coin, platelet hyporeactivity mediated by uremic toxins and anemia contributes to the increased bleeding risk in advanced CKD.
